Pretty neat game! I don't know anything about card games, but I clicked on some funny animals and won somehow!
I actually wished there'd been more of the card game compared to the VN, since it worked well and seemed fun. It'd have been cool if the other magical girls introduced new cards, too, or if there were new mechanics for having two characters on your side of the field. Since, as far as I could tell, it was essentially just the same battle and the same deck three times (other than one of the cards being gold and having buffed stats).
That said, the artwork for the characters and cards was very nice! The story and villain were fairly generic for a magical girl setting, but I guess that was probably the goal here. Though, I have to admit I started clicking through the dialogue after a while. On the other hand, having voice acting in a gamejam is always impressive!
Overall, good job!
